HELP! Questions about the EVENT-GROUP & TASK.
Posted: Tue Jan 22, 2019 6:52 am
I am new in ESP32.
In my project, it use BLE to scan the nearby beacon, and then use WIFI to upload the Beacon MAC address through TCP/IP protocol.
However, when the BLE-scan-service event works and calls the TCP-task, the break period is over.
It reminds me these:

About the two EVENT-GROUPS & one TASK, I am wondering how they will work successfully and how I can handle them in a right way.
It's quite a tough work to understand the official documents.

EVENT-GROUP:
static esp_err_t wifi_event_handler(void *ctx, system_event_t *event);
static void esp_gap_cb(esp_gap_ble_cb_event_t event, esp_ble_gap_cb_param_t *param);
TASK:
void TCP_Client_Message(unsigned char* Message);
In my project, it use BLE to scan the nearby beacon, and then use WIFI to upload the Beacon MAC address through TCP/IP protocol.
However, when the BLE-scan-service event works and calls the TCP-task, the break period is over.
